The scrimshaw can be activated on and off for a total of 3 hours after which it degrades to dust.

When activated, it gives the player a 15% chance to double the divine energy received when gathering memories (this applies even if a memory is not obtained). The scrimshaw will last for three hours of activated use before degrading to dust. The scrimshaw will work on all normal divination wisps/springs, including elder, negative, positive, and ancestral wisps and springs, and Divine-o-matic vacuum.

This scrimshaw is worth around 1,500 energy (at 99 Divination) if left constantly activated while training - 328,500 coins in incandescent energy. The duration (and thus the overall value) can be roughly doubled if deactivated when converting memories, as it has no effect then.
